Since his departure from Vampire Weekend earlier this year, Rostam Batmanglij has kept busy with new solo material — “EOS” and “Gravity Don’t Pull Me” — and a forthcomingcollaborative album with the Walkmen’s Hamilton Leithauser. During a guest DJ set and interview for KCRW, Batmanglij debuted new songs from both projects: His new solo track is called “Gwan” and it’s an operatic, emotional number that blends in seamlessly with the Radiohead track that follows it, and the new Leithauser collab is called “Sick As A Dog.” You can hear them below at 13m15s and 31m13s respectively.

His collaborative album with Leithauser, I Had A Dream That You Were Mine, is out 9/23 via Glassnote.
